Question CPU getting to low to mid 60s while under only 20-25% load

[AnthonyM79]

I just recently built a new SFF PC and while doing some testing to get a general idea what my thermals were I noticed that my CPU was getting decently high temperatures while not under much load. While playing Fallout 4 on mid/high settings I was getting around 240 FPS but my CPU was reaching an avg of 60ish degrees at around 20% load and a single core would go anywhere as high as 75-80 degrees while my GPU was hitting around 60 degrees as well. My radiator fans also needed to be at a pretty loud rpm to keep my CPU at those temps. I understand that with a SFF PC the thermals aren't going to be incredible or maybe this is normal but I just found this odd.

Specs:
i5 13600k
MSI Ventus RTX 3080 10gb
MSI Meg Z690I Unify
Corsair Vengeance 32gb DDR5-6000
EK AIO Basic 240
Corsair SF750 PSU
Lian Li Dan A4 H20

What are the temperatures at load? As you note, you ought to expect higher temperatures on average and you have a high-power system. Testing a mid-percentage like this isn't terribly useful.

While running cinebench for a few minutes my CPU was at 100% load and reached around 89 degrees.
Also for reference it runs at around 35-40 while idling.

With how the radiator is packed in there, and likely being used as an exhaust, the results ain't bad.
